Now ME1 didn't say single-core or dual, but anyone that ran a high-end single core knew it was pretty bad and we had a couple of hotfixes for us single-core users. So it would seem like they meant to put Dual-Core in those Reqs for ME1 but didn't state it.But, if you just look at the SysReq for the 3 games, besides the GPU, nothing has changed. I Applaud This! Between ME1 and ME2 the code was cleaned up so much that it looked so much better and ran a lot smoother. Also, ME3 has even a Lower CPU requirement (requires a little better GPU though) than ME2 and states 4G RAM for Vista/7, which usually goes without saying for games since 2010. It's the same DirectX, Same CPU, Same HDD Space (me1 was 12g where me2/3 are 15g).

So, the blanket question "I ran ME1 and ME2, can I run ME3?" can have the blanket answer, "Yes, and ummm Sure.. and Yup."
